OIL OR GAS BURNER.

SPECIFICATION forming part of Letters latent No. 471,753, dated March 29, 1892'.

Application filed January 1'7, 1891. Serial llo. 378,090. (No model.)

To aZZ whom it may concern:

Be it known thatI, GEORGE SMITH SANFORD, a citizen of the United States, residing at Mount Clemens, county of Macomb, State of -Michigan, have invented a certain new and useful Improvement in Oil or Gas Burners;

and I declare the following mm a full, clear,

removed. Fig. 3 is a plan View, partly in section and partly in elevation. Fig. 4 is a central sectional view of the same. Fig. 5 is an end view of the rear end of the burner. Fig. 6 is an inside view of the said rear end of the machine, showing the manifold oil-receiver. Fig. 7 is a sectional view showing the arrangement of the respective chambers and conduits, form of burner, and casing.

My invention has for its object the production of a burner for burning hydrocarbon oil, and more particularly for use with crude petroleum, the same being equally applicable for use in the burning of natural gas.

The particular features of my invention are hereinafter described, and will be more distinctly pointed out in the claims.

In carrying out my invention, A represents an oil-feeding conduit, and B a steam-supply conduit.

A is a chamberinto which oil is first introduced and from which it is led by several pipes A to a chamber A adjacent to the in-' are each projected into the nozzles B so that when a jet of steam issues from the nozzles A it acts as aninjector to draw in the oil from the chamber A and expel the same thoroughly commingled with the said steam from the nozzles B This action of the steam tends, also, to produce a vacuum in the chamber A and so draws the oil forward from the chamber A by suction into the chamber A. caused thus to enter the chamber A through the several pipes A is distributed with substantial uniformity throughout the said chamber A thus preventing an inordinate feed of oil from any particular nozzle B. the steam being fed to the chamber B preferably by several pipes B is uniformly distributed in the said steam-chamber, thereby causing the steam to issue with substantialuniformity from each of the said steam-nozzles A 0 represents a cover-plateat the extreme forward end of the burner, held in place by bolts 0 to the body 0 of the burner.

0 represents a central air-orifice, preferably provided with a tube 0 extending back through the chamber A at the rear end of the burner.

D is a shield surrounding the burner. It is preferably made cylindrical along its forward portion D, so as to uniformly distribute the entering air about the exterior of the burner; but it is preferably squared along the portion D so as to facilitate its being bricked into a stove-door or furnace-front.

D is a plate, which I prefer to provide at the rear end of the burner, and it may or mav not be cast solid with the chamber A, as showi1 in Fig. 4:. It is provided with any suitable air-governing valves or registers d for regulating the admission of air about the exterior cent to the forward end are preferably curved, 0

as shown at a, so that air entering through the case D shall not be deflected away from the burners, but be guided by this rounded surface directly to the base of the nozzles B The end portions 0 are likewise preferably curved, so as to prevent, as much as may be, any eddying of the on rrents, which would cause an nnuniform discharge of the air about the exterior of the burner at its forward end. The

discharge end of the central orifice O is like- I00 wise curved outwardly into bell form at 0 so that air entering may be directed to the bases This oil, 55

So, also, 60

for each steam-conduit for more perfectly regulating the admission of steam, and the.

valve on is provided for regulating the flow of oil or hydrocarbon into the chamber A.

I prefer to form the nozzles A of brass or The shield D termina'tes, preferably, a little back of the' forwardj end of the burner, so as to permit-the forward l end of the burner to become highly heated, 'thnsserving in a largemeasure to vaporize: the hydrocarbon before issuing from the noznon-oxidiza'ble metal.

Should the'cham ber -A 'become clogged with coke or other residuumythend C may re-g moved and the chamber cleared.

What I claim 'is- 1. An "oil orhydrocarbon burner composed" of the steam-chamber B oil-chamber A with their respective nozzles B and A and inletpipes B and A central air-passage C ,having a bell-mouth discharge end, whereby the air from said passage is permitted to pass outward directly to said nozzles, and a casing for conducting the air to said nozzles outside of said burner, the face of said burner support ing said nozzles being rounded to permit the air conducted to the burners by said casing to pass over said face directly to said nozzles,'

substantially as described.

2. Anoil or hydrocarbon burner consisting of the chambers A B with their respective nozzles A B oil-distributing chamber A, and

communicating oil and steam pipes, as described, the central air-conduit leading back' through the oil-distributing chambers, the

case D, a closing-plate atthe end ofthe burner, and means for regulatingthe admission of air through said case and central passage, substantially as described.

In testimony whereof I sign this specification in the presence of two witnesses.

GEORGE SMITH SANFORD.
